nvim-treesitter/queries/clojure/highlights.scm

; >> Explanation
; Parsers for lisps are a bit weird in that they just return the raw forms.
; This means we have to do a bit of extra work in the queries to get things
; highlighted as they should be.
;
; For the most part this means that some things have to be assigned multiple
; groups.
; By doing this we can add a basic capture and then later refine it with more
; specialized captures.
; This can mean that sometimes things are highlighted weirdly because they
; have multiple highlight groups applied to them.
